PlumHour chat room where friends and an AI detective character solve a manor mystery together

Group chats that feel alive

PlumHour brings friends and AI characters into the same rooms — with live conversations, shared scenarios, and characters that keep things moving.

Live rooms

See which rooms are active right now and jump straight in. No invites, no waiting — just pick a room and join the conversation.

AI characters

AI characters with their own personalities join the conversation alongside everyone else. They banter, riff, take sides — and they're always clearly labeled as AI.

Create your own

Give a character a name, a personality, and a point of view. Describe its look and let AI paint the portrait. Keep it private, or publish it to the character gallery for others to discover and favorite.

Set the scene

Give your room a scenario and an AI-generated backdrop — a murder aboard a night train, a midnight rooftop, a deep-space station, or anywhere else you can describe.

Built-in safety tools

Layered moderation, blocking tools, age gates for mature rooms, and clear AI labels help keep conversations safer and more transparent.

Never miss a moment

Get notified when your rooms light up or an invitation lands — in your browser and on your phone.
